GM to Spice-Up Cadillac and Buick

The once-mighty “GS” moniker will be coming back in the next year.  The GS series will be reserved as the sport trim for the Regal and LaCrosse sedans.  Cadillac will be sexed-up–somewhat–with a “V” edition of its CTS “sport wagon.”  If you need reminding, the CTS-V sedan features a 556 hp supercharged 6.2 L V-8, good for 0-60 times in four seconds.  We’re not sure about the investment in Buick, but the V-wagon sounds good.
